 696-784 2.27e-53

Helically-extended SH3 domain; This domain is the 70 C-terminal residues of ADAP - Adhesion and de-granulation promoting adapter protein. It shows homology to SH3 domains; however, conserved residues of the fold are absent. It thus represents an altered SH3 domain fold. An N-terminal, amphipathic, helix makes extensive contacts to residues of the regular SH3 domain fold thereby creating a composite surface with unusual surface properties. The domain can no longer bind conventional proline-rich peptides. There are key phosphorylation sites within the two hSH3 domains and it would appear that binding at these sites does not materially affect the folding of these regions although the equilibrium towards the unfolded state may be slightly altered. The binding partners of the hSH3 domains are still unknown.

 499-561 1.44e-06

Src Homology 3 domain superfamily; Src Homology 3 (SH3) domains are protein interaction domains that bind proline-rich ligands with moderate affinity and selectivity, preferentially to PxxP motifs. Thus, they are referred to as proline-recognition domains (PRDs). SH3 domains are less selective and show more diverse specificity compared to other PRDs. They have been shown to bind peptide sequences that lack the PxxP motif; examples include the PxxDY motif of Eps8 and the RKxxYxxY sequence in SKAP55. SH3 domain containing proteins play versatile and diverse roles in the cell, including the regulation of enzymes, changing the subcellular localization of signaling pathway components, and mediating the formation of multiprotein complex assemblies, among others. Many members of this superfamily are adaptor proteins that associate with a number of protein partners, facilitating complex formation and signal transduction.

 695-766 1.36e-37

Helically extended Src Homology 3 domain of Adhesion and Degranulation-promoting Adaptor Protein; ADAP, also called Fyn T-binding protein (FYB) or SLP-76-associated protein (SLAP), is expressed mainly in hematopoietic cells but not in B cells. It is required for the proliferation of mature T-cells and plays an important role in T-cell activation, TCR-induced integrin clustering, and T-cell adhesion. ADAP has been shown to bind many partners including SLP-76, Fyn, Src, SKAP1, SKAP2, dynein, Ena/VASP, Carma1, among others. It is connected to cytoskeleton via its binding to Ena and VASP, which impacts actin cytoskeletal remodeling upon TCR ligation. The SH3 domain of ADAP adopts an altered fold referred to as a helically extended SH3 (hSH3) domain characterized by clusters of positive charges. The hSH3 domain can no longer bind conventional proline-rich peptides, instead, it functions as a novel lipid interaction domain and can bind acidic lipids such as phosphatidylserine, phosphatidylinositol, phosphatidic acid, and polyphosphoinositides.

Helically extended Src Homology 3 domain of Adhesion and Degranulation-promoting Adaptor Protein; ADAP, also called Fyn T-binding protein (FYB) or SLP-76-associated protein (SLAP), is expressed mainly in hematopoietic cells but not in B cells. It is required for the proliferation of mature T-cells and plays an important role in T-cell activation, TCR-induced integrin clustering, and T-cell adhesion. ADAP has been shown to bind many partners including SLP-76, Fyn, Src, SKAP1, SKAP2, dynein, Ena/VASP, Carma1, among others. It is connected to cytoskeleton via its binding to Ena and VASP, which impacts actin cytoskeletal remodeling upon TCR ligation. The SH3 domain of ADAP adopts an altered fold referred to as a helically extended SH3 (hSH3) domain characterized by clusters of positive charges. The hSH3 domain can no longer bind conventional proline-rich peptides, instead, it functions as a novel lipid interaction domain and can bind acidic lipids such as phosphatidylserine, phosphatidylinositol, phosphatidic acid, and polyphosphoinositides.

 514-561 7.63e-04

Src Homology 3 domain superfamily; Src Homology 3 (SH3) domains are protein interaction domains that bind proline-rich ligands with moderate affinity and selectivity, preferentially to PxxP motifs. Thus, they are referred to as proline-recognition domains (PRDs). SH3 domains are less selective and show more diverse specificity compared to other PRDs. They have been shown to bind peptide sequences that lack the PxxP motif; examples include the PxxDY motif of Eps8 and the RKxxYxxY sequence in SKAP55. SH3 domain containing proteins play versatile and diverse roles in the cell, including the regulation of enzymes, changing the subcellular localization of signaling pathway components, and mediating the formation of multiprotein complex assemblies, among others. Many members of this superfamily are adaptor proteins that associate with a number of protein partners, facilitating complex formation and signal transduction.

Third Src Homology 3 domain of Nck adaptor proteins; This group contains the third SH3 domain of Nck, the first SH3 domain of Caenorhabditis elegans Ced-2 (Cell death abnormality protein 2), and similar domains. Nck adaptor proteins regulate actin cytoskeleton dynamics by linking proline-rich effector molecules to protein tyrosine kinases and phosphorylated signaling intermediates. They contain three SH3 domains and a C-terminal SH2 domain. They function downstream of the PDGFbeta receptor and are involved in Rho GTPase signaling and actin dynamics. Vertebrates contain two Nck adaptor proteins: Nck1 (also called Nckalpha) and Nck2 (also called Nckbeta or Growth factor receptor-bound protein 4, Grb4), which show partly overlapping functions but also bind distinct targets. Their SH3 domains are involved in recruiting downstream effector molecules, such as the N-WASP/Arp2/3 complex, which when activated induces actin polymerization that results in the production of pedestals, or protrusions of the plasma membrane. The third SH3 domain of Nck appears to prefer ligands with a PxAPxR motif. SH3 domains are protein interaction domains that usually bind to proline-rich ligands with moderate affinity and selectivity, preferentially a PxxP motif. Ced-2 is a cell corpse engulfment protein that interacts with Ced-5 in a pathway that regulates the activation of Ced-10, a Rac small GTPase.
